Description

Technical Field

[0001] This utility model belongs to the field of air source heat pump technology, and in particular relates to a noise reduction unit for a dual heat source air source heat pump. Background Technology

[0002] Dual-source air source heat pumps use an air source heat pump as the main unit, absorbing heat energy from the air to provide heating / cooling. They can also be connected to auxiliary heat sources such as gas-fired wall-mounted boilers to achieve combined heating and cooling. For example, in low-temperature environments, the wall-mounted boiler can assist in heating the water to maintain the heat pump's efficient operation; in high-temperature environments, the heat pump alone handles both cooling and heating.

[0003] Chinese patent CN213873717U discloses a noise reduction device for an air-source heat pump drying and dehumidifying unit. The device includes a base plate and a housing. The top of the base plate is fixedly connected to the bottom of the housing. The housing's interior bottom is fixedly connected to the unit body. The left and right ends of the housing each have through-slots. Noise-reducing plates are fixedly connected inside these slots. Multiple through-holes are evenly distributed on the ends of the two noise-reducing plates furthest from the center of the housing. A fixing plate is fixedly connected to the top of the housing's interior. Support plates are fixedly connected to the bottom left and right sides of the fixing plate. A T-shaped plate is fixedly connected to the bottom of the fixed plate. The T-shaped plate is located between two support plates. Motors are installed on the top left and right sides of the T-shaped plate. The output end of the motor is fixedly connected to a rotating shaft. The ends of the two rotating shafts away from the center of the box pass through the support plates and are fixedly connected to a fan. The noise reduction device of this air source heat pump drying and dehumidifying unit uses noise reduction plates set at the left and right ends of the box. The interior of the noise reduction plates has been modified to have uniquely shaped sound-absorbing holes, which enhances the noise reduction effect and makes the noise reduction effect obvious. The motors fixed to the support plates can drive the motors to rotate the rotating shafts, which in turn rotates the fan, allowing the air in the box to circulate and achieve the heat dissipation effect.

[0004] However, in the above solution, the unit is installed inside the enclosure, and the sound of the unit can still be transmitted to the outside through the enclosure during operation, making it difficult to achieve a relatively efficient noise reduction effect.

[0035] In this embodiment, air enters through the air inlet and carries away the heat from the surface of the serpentine heat sink 401 to the air outlet for heat dissipation, thus enabling air circulation and heat dissipation inside the support frame 301.

[0036] In a further preferred embodiment of this utility model, the upper and lower sides of the serpentine heat dissipation pipe 401 are respectively far away from the noise reduction box 1 and the support frame 301.
